Why do plants (bean plants) need water as their source of liquid? What will liquids such as milk, coffee, pepsi or lemonade do in place of the water?

Seeds are dry and have a hard seed coat. In order to get the seed coat to split, they must imbibe (soak up water) which makes them swell and cracks the seed coat. The liquids you were speaking of are still mostly water and will all probably work. How well? Well, that's an experiment!
